18×K7 Compacted Strand Wire Rope

18xK7-WSC

Short Description:

Compacted Strand Wire Rope is designed for demanding, high-performance applications that require a combination of strength, durability, and flexibility. It is widely used in industries like construction, mining, maritime, and heavy machinery.

Product Detail

18×K7 Compacted Strand Wire Rope

18×K7 Compacted Strand Wire Rope is engineered for superior strength, durability, and performance in heavy-duty lifting and hoisting applications. During manufacturing, each strand undergoes a precision compaction process, compressing individual wires tightly together to reduce internal gaps. This creates a denser and stronger rope structure compared to conventional wire ropes, making it ideal for high-load, high-intensity operations.

Key Features

High-Strength Compacted Structure
The compacted strands increase metal cross-section density, boosting tensile strength and minimizing internal friction. This ensures stable performance under heavy loads.

Superior Load-Bearing Capacity
Thanks to its dense and uniform construction, the rope can handle significantly higher loads—perfect for cranes, hoisting systems, and industrial lifting machinery.

Exceptional Wear and Fatigue Resistance
The smooth and compact surface minimizes internal wire movement, reducing abrasion and enhancing fatigue resistance during repeated bending cycles.

Extended Service Life
Manufactured from high-grade steel and processed with precision heat treatment, the rope offers long-term reliability and minimal maintenance in harsh environments.

Excellent Flexibility
Despite its compacted structure, the rope maintains excellent flexibility, ensuring smooth winding and unwinding in dynamic lifting conditions.

Construction Options

  • 18×K7 – Optimized for superior strength, stability, and controlled flexibility.

  • 18×K19S – Designed for enhanced fatigue resistance and smoother surface contact in dynamic applications.

Typical Applications

The 18×K7 Compacted Strand Wire Rope is widely used as a lifting rope for:

  • Mobile cranes and vessel cranes

  • Tower cranes and bridge cranes

  • Cantilever cranes and pile drivers

  • Rotary drilling rigs and other heavy lifting systems

It performs exceptionally well in operations where one end can rotate freely or lift to considerable heights.
